T0 all whom t may concern: j

Be it known that I, VICTOR NIEwINsKI, a citizen of Russia, residing atSt. Paul, in the county of Ramsey and State of Minnesota,

have invented certain new and useful Imervoir may be utilized as fullyas desired for the operation of a fanor other air engine.

A third importa-nt object of the invention is to provide an improvedarrangement of this character wherein the fan engine is mounted forvarying position on the reservoir casing so that the blast of air fromthe fan may be cont-rolled in direction.

With the above and other obj ects in view. as will be hereinafterapparent the invention consists in general of certain novel details `ofconstruction and combinations of parts hereinafter fully described,illustrated in the accompanying drawing, and specilically claimed.

In the accompanying drawing, like characters of reference indicate likeparts in the several views, and

Figure 1 is a vertical section through the casing of a device of thischaracter showing the reservoir, the fan and its engine being shown inelevation. 2 -1 Fig. 2 is a top plan view of the reservoir, the fansupporting pipe being shown in section.

Fig. 3 is a vertical section through the reservoir at right angles toFig. 1.

Fig. 4 is a section on the line 4.-4 of Fig. 1.

Fig. 5 is a section on the line 5-5 of Fig. 4.

Fig. 6 is avertical section partly in elevation through the fan.

Fig. 7 is a vertical section through a union j employed herewith.

Fig. 8 is a section on the line 10H10 of Fig. 6.

Fig. 9 is a` section on the line 11 11 of Fig. 6.

In carrying out the objects of this invention there is provided a casinghaving side walls 10 and a bottom 11. Within this casing is slidablymounted a plunger 12 which constitutes the top' wall of the reservoirland which is provided around its periphery with suitable packing 13 toform an air tightjoint. Projecting from the upper corners of the plunger12 are coil compression springs 15 which constantly urge the plunger l2downward. In order to prevent too great movement of this plunger stops16 are provided within the casing adjacent the lower end thereof.Extending across the lower part of the casing is a diaphragm 17 whichseparates the casing into upper and lower chambers and extendingtransversely across the casing beneath this diaphragm is a` partition18. On one side of this partition the diaphragm 17 is provided with anopening 19 controlled by a check valve 20 so that air may pass upwardthrough this opening 19 but can not pass downward. Within the lowerchamber of the casing on the side of the diaphragm 18 opposite th'.Jopening 19 arel cylinders 21. The cylinders 21 are of the ordinary pumpcylinder type and are screwed into the partition 18 so that their endsare flush with the face of the partition which is adjacent the opening19. These ends are preferably screwed into the respective cylinders asshown at 23 and each end is provided with an opening 24 controlled by acheck valve 25 opening outwardly from the cylinder. In each of thesecylinders there is a piston 26 having an opening 27 therein controlledby a check valve 28 just as in an ordinary flat valve pump. Thesepistons 26 are connected by piston rods 29 to a crank shaft 30 journaledin the sides of the casing and provided at one end with a handled crank31. Now by means of this arrangement air from the intake chamber whichis admitted from the atmosphere by ports 43, will be pumped uponrotation of the crank 31, into the receiving chamber beneath the valve2O and thus force air into the body of the reservoir causing the plunger12 to riset` As the plunger' 12 rises the springslv are coinpressed sothat there is stored in the reservoir by this means a body of compressedair of comparatively great quantity. Ex'- tending from the lower part ofthe reservoir upward is a pipe the upper end of which is turned upwardvertically as at 4 6 and on this upper end is mounted a swiveling union47 carrying a worm wheel 48. Projecting upward from the union is a pipe49 having a valve 50 therein, the pipe 49 `forming practically anextension of the union and having mountedon its upper end a yoke 51which is pivoted on horizontal axes 52. Extending from the pipe 49 is abracket 58 'where through passes an adjusting screw 54 having its endswiveled in the lower arm of the yoke and between. this roller arm andthe bracket 58 is a coil spring 55. By means of movement of thisadjusting screw 54 the angular relation of the yoke to the union may bechanged. Mounted between the upper 'arms of the yoke 51 is a blowercasing 56 which communicates by means of a flexible pipe 57 with thepipe 49. Vithin the blower casing is a rotor 60 here illustrated astyp`i- `cal of animpact rotor as'can be seen by referenc'e to Fig. 6,the casing'beingprovided with the usual exhaust port 61. This rotor' isfixed on a shaft 62 Icarrying at one end a fan 63. Now by means of thisconstruction Ithe compressed air from the reservoir will crank 31 thefan may be caused to continuously rotate about the axis of the pipe 49.`

A suitable safety valye 67 is provided on the plunger l2 to prevent toogreat charging of the reservoir.

In operation after the reservoir has been charged in the manner asdescribed above the valve 50 is opened and it will be observed copiesfuns patent may be attained fer that by proper adjustment of the yokeand swivel the current of air from the fan may be caused to flow lin anydesired direction. This operation will continue until all of the air hasbeen exhausted from the reservoir when the latter may, be recharged byhand as previously describedl There has thus been provided a simple andefficient device of the kind described and for thepurpose specified.

It is obvious that many minor changes may bernadein tli'e" form andconstruction of the invention without departing fromthematerialprinciples thereof Itis not therefore desired to conlilietheinvention to the exact foi-in herein shown ancl` d'escri'bed but it'is wished to' include all such" as properly corne within the' scopecl'a'iined.

Having thus described the invention, what is claimed as new, is

1. In a devicetof the kind described, a casing constituting areservoir'and having' a plunger movable therein toward and from one endof said reservoir, means constantly urging said plunger toward saidend`an air compressor" in the reservoir arranged to force air into thecasing and thereby urge the plunger away frorn'saidend, a pipe leadingupward from the reservoir and having its upper end vertical, aswivelingl union` 0n the upper end ofthe pipe, and "airengine mounted onand communicating with-the union.

2. In a device of thev` kind described, a casing constituting reservoirandhaving a plunger movabletherein toward and'from one end of saidreservoir, means constantly urging said plungertoward said end, an aircompressor in the reservoir arranged to force air into the casing andthereby urge the plungerl away from said end,-- a; pipe leading upwardfrom the reservoir vandh'aving'its upper end vertical, a swivelingunionon the upper end ofthe pipe, a yoke pivoted to said union toswing ongahorizontalaxis, means to kadjust the angular relation ofthe yoke andunion, an air engine carried by said yoke', and a-fielible'pipeconnecting the union and engine.

In testimony whereof I Iny'fsignature.
